0.0

Sharing my best sleep ever. This result comes 2 weeks after using new ASV. Results have been good every night, but not this good.
Not even one hypopnea showed up until one was detected after the noon cutoff.

Whoo Hooo!!! Good feeling isn't it? I had a couple 0.0.nights recently also. Usually when someone posts about a 0.0 night someone eventually posts that it doesn't matter for one reason or another blaming the machine or what not. Intellectually, that may be true but emotionally it sure is a boost.

Great News!!!

The results you are getting with your machine are often the results one sees with modern ASV technology. After all, that's exactly what a ventilator is supposed to do - it steps in and forces you to breathe using very high pressures only when your brain and/or neural system screw up and forget to send out the proper signals. It's been doing it with preemie babies, coma patients and people with certain types of lung disease for half a century. Probably before that if you consider 'iron lungs'. (Note: ASV is generally contraindicated for people with COPD and congestive heart failure, plus a few other more rare conditions). Yes indeed, it is a genuine miracle thanks to the modern world and medical research.

However, for me, the real miracle is how anyone can afford an ASV machine. Example https://www.cpap.com/productpage/pr-60- ... anced.html

And that's without a hose, humidifier or mask PS... there was one being sold in the SF Bay area recently for $500. Wonder what happened to it?

Congrats! I have a 0.0 night once in a while, and it DOES feel good.

Excellent news and results! If I am remembering correctly, hasn't the move to ASV been more recent? If so, that is great that you are responding so favorably to ASV therapy. When everything just 'clicks' with our therapy it is wonderful. I am sure you would agree that for those still waiting for their PAP therapy to 'click' that giving up will never get you there. You have to just keep fighting...

+1!! I always cringe when someone rains on the 0.0 AHI parade. Like you say, if it is real or placebo, it doesn't really matter. I say lets celebrate with them whether we have or haven't experienced it ourselves, what does that hurt?

Congrats on that great 0.0 result.

I was prescrbed an ASV machine and after fighting with the Insurer over it (and not getting therapy during that time), I reached into my pocket to acquire it. I went to a supplier mentioned here (not sure if I can name names) that sells "Open Box" and "Gently Used" machines and paid $1425. That was for a Respironics AutoSV Advanced which was a zero hour machine with the full manufacturers two year warranty. Still quite a bit but substantially less than the price quoted above.

Also, the supplier was great, spent quite a bit of time on the phine pre and post sale answering my questions and would definitiely be my choice over my know nothing DME.

Papit, as an ex engineer, as you're, I am questioning why the values of any of the Events in your Stats are NOT shown with a number of zero? The AHI is a combination of events which are usually shown in the ResScan Stats with numbers and not hyphens.

Another issue is that ResScan while identifying your machine as an Adapt ASV should NOT have shown in the Stats an entry for Central events.

Could you please show the Stats, with same ResScan setup, for the 3 previous nights?

Congrats!! So the worst that can happen is that the machine "malfunctioned" and you really had an AHI=0.1!

[avi123]

This poster with two nights of AHI = 0 results, on VPAP Adapt (mode =ASV), would also be questionable:

viewtopic/t82750/finally-on-ASV-0-AHI-but-restless.html

Notice: Max EPAP = -1000000000.00

and in the Sheikh's post there: My AHI is usually at zero too, on the ResMed Adapt. BUT, on the PR AutoSv ASV, I find I have some flow limitation events, a few vibratory snore events and even an ocassional periodic breathing event. These are no worry cuz my O2 stays up above 94% all night. The PR Auto Advanced seems more senstive.

Why show on SH and not on ResScan, since the machine is ResMed's.

avi123, that is NO LONGER TRUE with the S9 ASV units!! While it's not certain (I don't have the unit to check personally), the clinician's manual notes that the S9 ASV unit records the Central Apnea Index. That is stored in the SD card and accessible on ResScan reports and within the ASV unit itself. It is possible the manual is incorrect, but I would want to confirm it with an advanced data head, who happens to also be an S9 ASV user.

Way to go, Papit.

Comment,

Hi John, I could not find data from such a machine showing values of Central events that were untreated (i.e. to have an entry for CAI)?

For example take this by Papit, from the other thread, that the ResScan Events graph will NOT show CAIs (if Pappit would stick to this ResScan graph for a moment, and expand the Events graph downwards, to show its full hight):

{to see the whole time length of the graph keep your Window un zoomed}

Gents, here are the detailed graphs, including Events, for that day (June 26) at full height. ResScan does not break out Apnea on the Events graph; i.e., Centrals and Objectives data are NOT separately quantified -- even though titles for each are shown, on my screen they are always followed by two hyphens for the S9 VPAP Adapt ASV machine. Each "Apnea" is shown on the detailed graphs page in red without distinguishing between the two types and each hypopnea as a small black rectangle. SleepyHead graphs the data in the same fashion for me. The Reports pages report the same way in both software programs.

That has not been my experience, John.

See: viewtopic.php?f=1&t=74249&p=682719&hilit=fot*#p682719

and idamtnboy's work on this:

I think I've got it figured out. It's the absence of FOT. Resmed uses what they call forced oscillation technique (FOT) to determine if an apnea is an obstructive or central apnea. I do not see that signal in the Adapt flow graph. You can clearly see the FOT signal on my CA and OA graph segments below but not in the Apnea graph segment from your data.

Maybe papit has a newer model machine with the same name??? Or just a mixed data file?
